Question

Python 3

Write a program that calculates the factorial of the greatest odd number in a sequence of positive numbers (separated by spaces). The program must receive sequences of integers, one per line. The end of the input cases will be indicated by the number -1. For each line the program must print the factorial of the greatest odd number in each sequence. Note that for this question, there is always a greatest positive odd number in each line.

Sample Input

4 3 5 8 10 1
1 1 0 2 3 3 4
8 3 5 0 0 1 7
-1

Sample Output

120
6
5040

Answer 1

def factorial(n):
    if n == 0:
        return 1
    else:
        return n * factorial(n - 1)


def main():
    while True:
        data = input()
        if data == "-1":
            break
        lst = [int(x) for x in data.split()]
        max_odd = 0
        for num in lst:
            if num % 2 == 1 and num > max_odd:
                max_odd = num
        print(factorial(max_odd))


if __name__ == '__main__':
    main()
